The cheapest way to send US dollars to South Korean won right now is usually a specialist provider such as Wise, which hands you the real mid-market rate and adds a small, clearly shown fee. On a $1,000 send that works out to roughly $7.25, or about 0.73% of the amount.
A US bank doing the same transfer often takes 3% or more, most of it hidden inside a worse exchange rate. This route carries family support, tuition and gifts within the Korean-American community, and with South Korea's high bank penetration the money almost always arrives as a bank deposit. The figures here are modelled estimates, so confirm the final price on the provider's own site before you transfer.
- A specialist beats the bank on almost every amount. Providers like Wise charge well under 1% all-in, while a typical US bank takes 3% or more, mostly hidden in the rate.
- The winner depends on how much you send. Small sends favour one provider and large sends another, so check the modelled tables below for your exact amount.
- The exchange-rate markup is the real cost. A low advertised fee can hide a poor rate, so compare the all-in cost, not the fee on its own.
- Bank deposit is the standard payout. South Korea has near-universal banking, so the money almost always lands in an account and cash pickup is rarely needed.
The cheapest way to send dollars to won
Send $1,000 and the providers that pass on the real rate come out on top. The table below ranks every option we track, from the cheapest at the top to the dearest at the bottom, using today's mid-market rate of about 1,371.15 won to the dollar.
For a plain bank deposit, Wise sits near the top: it gives you that mid-market rate and adds a fee of about $7.25, roughly 0.73% of what you send. The number you see at checkout is the number you pay, with no weekend surcharge and no monthly limit to watch.
The remittance specialists, WorldRemit and Remitly, are built for family support and add cash pickup, but with bank accounts so widespread in South Korea that option rarely matters. For a simple bank deposit their markups usually leave them a little higher on cost. The big banks sit at the bottom of the table, often past 3%.
The markup is what catches people who only glance at the fee. A provider can advertise "zero fees" and still deliver fewer won than a rival that charges a small fee and a fair rate. On a $1,000 send, the gap between a 0.5% all-in cost and a 3.5% one is about $30, which is a month of groceries.
Sending a larger amount
Push the amount to $10,000 and the picture can shift. A fixed fee barely registers on a big transfer, so a provider with a low percentage cost pulls ahead, while a provider with a flat fee looks cheaper than it did on a small send. The modelled table below shows the current order.
The lesson is simple: never assume the winner at $1,000 is still the winner at $10,000. Re-run the comparison for the amount you actually plan to send. At this size the stakes are bigger too. A 3% markup on $10,000 keeps about $300, while a 0.5% all-in cost keeps about $50. If you send to family every month, one larger transfer is often cheaper than several small ones, because you pay any fixed fee just once.
KRW can appear in specialised brokerage currency functionality, but the public withdrawal-fee list from Interactive Brokers does not include won. Do not use its headline FX commission as a USD-to-KRW delivery estimate; compare a provider that explicitly quotes the Korean bank deposit.
What affects the cost
Four things decide what a transfer really costs.
The fee. This is the charge you can see, either a fixed amount or a percentage of what you send. Wise, for instance, charges a small percentage plus a tiny fixed amount, both shown before you confirm. A fee is easy to spot, which is exactly why some providers keep it low and make their money somewhere else.
The markup. This is the hidden part, baked into a worse exchange rate. Western Union and MoneyGram often advertise a small fee, or none at all, but the markup is usually where their real cost sits. Two providers can quote the same fee and still deliver very different amounts of won, because of the rate. Our guide to markup versus transfer fee explains the difference in full.
The amount. A fixed fee shrinks as a share of a big transfer and grows on a small one. A percentage cost stays flat whatever you send. So the cheapest provider for $200 is not always the cheapest for $20,000.
The provider. Specialist fintechs and remittance firms price this route to win your business, and big US banks do not, which shows. The gap between the best and the worst option here is often several percent, and on a large send that is real money.
Who should use what
Use Wise if you want the simplest, cheapest bank deposit and you do not need cash in hand. It gives you the real mid-market rate and a small, clearly shown fee, the same price every time, with no weekend surcharge. Our Wise review has the full picture.
Use a remittance specialist like WorldRemit or Remitly if your recipient genuinely needs cash in hand rather than a bank deposit. That is rare in South Korea, where bank accounts are near-universal, but if it applies their agent networks can deliver the money the same day. For a plain bank deposit, though, they usually cost more than Wise.
Use your bank only if you have no other option. A typical US bank adds around 3% or more, most of it hidden in the rate, plus a wire fee on top. Switching to a specialist is the single biggest saving you can make on this route, and our guide to cutting FX fees shows how. The full comparison tool ranks every option for your exact amount.
Frequently asked questions
Is Wise the cheapest way to send money to South Korea?
For a bank deposit, usually yes. Wise passes on the real mid-market rate and adds a small fee, which tends to make it one of the cheapest options on this route. The exact ranking still depends on the amount you send, so it is worth checking the modelled tables above for your own transfer before you decide.
Can my family pick up cash instead of a bank deposit?
They can, through operators such as Western Union and MoneyGram, but it is rarely needed. Bank account ownership in South Korea is close to universal, so almost every send arrives as a deposit. Cash pickup also costs a little more, because the provider charges a higher markup, so a bank deposit is the better deal when both are available.
Are the fees shown here exact?
They use the current mid-market reference and, where available, a Wise account-holder API estimate. Other providers use stored published fee and markup models, not live quotes. Real prices vary by provider, by the amount you send, by how you pay, and by how the money arrives. Always confirm the final figure on the provider's own site before you transfer.
Cost figures are worked out from each provider's published fee structure applied to the current mid-market reference rate. They are modelled estimates for this route, not live quotes, and availability and exact pricing vary by provider, by payment method and by payout method (bank deposit versus cash pickup). Always confirm the final figure on the provider's own site before you send. We may earn a commission from affiliate links at no extra cost to you; this never affects our rankings.
